High temperature resistant silicone material is one of the indispensable important materials in automobile manufacturing. It can not only optimize the automobile manufacturing process, but also improve the performance and safety of the automobile. It has been widely used in various parts of automobiles, such as airbag coating. Layers, power transmission seals, gaskets, hoses, windshield linings, automotive engine seals, ignition wires and coil jackets, automotive turbocharger cooling pipes, automotive component seals and protection, high voltage cables and wiring harness seals Wait.
Compared with traditional fuel vehicles, hybrid and pure electric vehicles have added a lot of high-voltage accessories, such as power batteries, high-voltage power distribution boxes, drive motors, and motor controllers. This also puts forward new requirements for automotive cables. Because these cables are arranged in the area of the front cabin engine and chassis, the temperature is high, the space is small, the cables need to be soft, the turning radius is small, and the high and low temperature resistance is good; secondly, the road conditions are complicated, the cable must have good abrasion resistance and high mechanical strength; In addition, the vehicle speed is high and low, especially under severe working conditions such as full-load climbing, and the instantaneous high current requires the cable to have short-term overload capacity.
In summary, new energy vehicle cables must have: good electrical insulation properties; thermal stability and weather resistance; corrosion resistance, oil and water resistance, and excellent flame retardancy; superior comprehensive mechanical properties, high flexibility and high tear resistance Crack and so on.
